I'm developing a plugin for WordPress which has 3 groups of users. I need to disable some users and prevent them from login. what I mean isn't preventing them to access the backend. I want to prevent them from is log in. For example, when they want to login they should see a message like this account isn't active yet. thank you guys.
after some search and see similar problems I solved this problam like this : first add a user meta for user status so we can checking if user is active or not then we can disable or enable users.
add_filter( 'authenticate', 'chk_active_user',100,2);
function chk_active_user ($user,$username)
{
$user_data = $user->data;
$user_id = $user_data->ID;
$user_sts = get_user_meta($user_id,"user_active_status",true);
if ($user_sts==="no")
{
return new WP_Error( 'disabled_account','this account is disabled');
}
else
{
return $user;
}
return $user;
}
